I have tried to unsubscribe from the Colorsync-users list numerous times by clicking the "unsubscribe button" on the appropriate page . All without success.

Did you receive an unsubscribe email from the server? You need to respond to the email otherwise you’ll remain subscribed. If you didn’t get an email then try unsubscribing by sending a message to: colorsync-users-leave@lists.apple.com Which will initiate the unsubscribe process if the web interface isn’t working (providing Apple haven’t altered or disabled Mailman’s standard features). -- Martin Orpen Idea Digital Imaging Lt
